Playing video and content build in PPT 2007

Hello Lounge!
I need a trick to do what I want to do in PPT. I need to play a three-minute long video (mp4, but I could convert). While the video plays, I want to add explanatory notes for certain parts of the video. I'm pretty handy, but this one has me stumped.

Using: PPT 2007, Win 7

I set up these notes initially in text boxes, designed to look like a marker on a white board. Used custom animation by letter -- then wipe text off. Very cool. Made a new text box for each comment.

Set up the video to play automatically, then text boxes "follow previous" with the timing set according to when the comments should appear. I initially used a generic blank slide.

Video ran, but no text boxes.

Then I switched to a new blank presentation and tried the layout with content on both the right and left sides of the slide. Video on left side and comments on the right side. Again, video plays fine, but comments do not appear on timing. I tried setting the content to appear with mouse click, but the mouse click stops the video.

I understand that PPT 2007 is designed for the video to always be on top of other items, but I thought I could get around that by using the two-content slide layout.

I cannot figure out how to keep the video running while the content appears. I don't mind clicking to activate the comments entrance and exit, but I need to somehow isolate the video from responding to mouse clicks. Or, any other trick that would allow this.
